11月(yue)11日，西北電(dian)網外(wai)送(song)(song)(song)電(dian)量(liang)(liang)達到1.051億(yi)千瓦時(shi)，單日外(wai)送(song)(song)(song)電(dian)量(liang)(liang)首次突破1億(yi)千瓦時(shi)大關，外(wai)送(song)(song)(song)最大負荷達511萬千瓦，占目前西北外(wai)送(song)(song)(song)總容量(liang)(liang)的83.63%，日外(wai)送(song)(song)(song)電(dian)量(liang)(liang)和外(wai)送(song)(song)(song)負荷均創歷史新高。
隨著寧東(dong)—山(shan)東(dong)±660千(qian)(qian)伏直流輸(shu)電(dian)示范(fan)工程(cheng)順利投入試運行，西北(bei)(bei)電(dian)網(wang)(wang)外送最大(da)容(rong)量達到611萬千(qian)(qian)瓦，西北(bei)(bei)外向型、送出型、規模型堅(jian)強送端(duan)電(dian)網(wang)(wang)已初具規模，實現西北(bei)(bei)—華北(bei)(bei)、西北(bei)(bei)—華中(zhong)聯(lian)網(wang)(wang)，將黃河(he)上游水(shui)電(dian)、煤電(dian)基地火電(dian)打捆(kun)送往四川、山(shan)東(dong)，有(you)力推進西北(bei)(bei)能源資源在更(geng)大(da)范(fan)圍內優(you)化(hua)配置，為緩解冬(dong)季(ji)華中(zhong)、華北(bei)(bei)電(dian)網(wang)(wang)缺電(dian)局面(mian)提供了強大(da)的電(dian)力支撐。
為應對外(wai)送負荷和網(wang)(wang)(wang)內用電(dian)(dian)負荷高峰的到來，確(que)保迎(ying)峰度冬(dong)和大(da)負荷外(wai)送期間電(dian)(dian)網(wang)(wang)(wang)安全穩定運行，西北電(dian)(dian)網(wang)(wang)(wang)有限(xian)公司加快全網(wang)(wang)(wang)檢(jian)修和設備投產速度，目前已實現750千伏(fu)統(tong)一電(dian)(dian)網(wang)(wang)(wang)覆蓋西北五省（區），強化了(le)西北送端網(wang)(wang)(wang)架結構。
西(xi)北(bei)公司還指(zhi)導主要火(huo)電(dian)(dian)發電(dian)(dian)企業簽(qian)訂了年(nian)利用(yong)5000小(xiao)時以上(shang)的(de)中長(chang)期合同，以黃河(he)富余水電(dian)(dian)進行短期調節，充(chong)分發揮“電(dian)(dian)量(liang)庫(ku)”交易機(ji)制，提(ti)前做好外送(song)(song)電(dian)(dian)力(li)電(dian)(dian)量(liang)組織(zhi)工(gong)(gong)作。同時，密(mi)切關注天氣變化，提(ti)高(gao)負荷預(yu)測的(de)準確(que)性，合理安排機(ji)組開機(ji)方式，加大電(dian)(dian)煤儲(chu)運工(gong)(gong)作力(li)度，提(ti)前落實全網發用(yong)電(dian)(dian)平(ping)衡。此(ci)外，西(xi)北(bei)公司還將(jiang)440萬千瓦火(huo)電(dian)(dian)裝機(ji)列入外送(song)(song)裝機(ji)序(xu)列，協(xie)調西(xi)北(bei)區域內主要水、火(huo)電(dian)(dian)廠留(liu)足備用(yong)容量(liang)，提(ti)前做好電(dian)(dian)力(li)電(dian)(dian)量(liang)平(ping)衡工(gong)(gong)作。
